Hi guys,
I am trying to see how can i generate a high ac voltage (sinusoidal 2000v peak to peak) from a battery (say 3.7v) source.
I need the ac to be as close as possible to a sine wave, and the frequency range is more or less audio: 100hz - 10khz.
I looked at the power supplies people use for tesla coils and other high voltage projects, and i even took apart a high voltage based insect killer to see how it works.
They all seem to use high voltage DC pulses, so I am turning for some advice here at the forum: what would be a quick and dirty, ideally low cost way of generating such a voltage ?
My power requirements are relatively modest, 2000v p2p voltage and 100ua of current, i.e. 1000*0.707*100e-6 = 70mw or so. I might want to go higher in voltage , i.e. 20kv p2p with 1ma of current, leading to 7w of power, but this is for later, assuming the basic experiment works ;-) so it would be nice if the solution would be somewhat scalable.
Thanks for all the advice !
Regards,
Lenny
